Those are just a few of thousands of chilling details in a 1,300-page report released by the Sparks Police Department on Tuesday, almost seven months after seventh-grader Jose Reyes killed Landsberry and shot and injured two students before killing himself.

On Oct. 21, Reyes brought a 9-mm semi-automatic pistol to school from home and, just before the first bell, terrorized hundreds of students and staff, according to heartbreaking testimony in the report.

The investigation included search warrants ranging from Reyes' locker and his home to school files, including of those who were injured. Even yearbook photos of every Sparks Middle School student were gathered to identify children in surveillance video.

And although there are hundreds of witness statements, letters from Reyes written to his parents and the school, documented cases where the 12-year-old was mistreated by classmates and questions surrounding his social and academic background, police said there is no one motive.

"The investigation did not identify one clear catalyst or motive for the actions of the suspect," Sparks Police Chief Brian Allen said.

The report included witnesses describing in detail hearing what they thought were firecrackers or someone popping a lunch bag before seeing Reyes wave a silver and black gun and shoot Landsberry.

What police found

Police described a boy who owned violent video games, used the family's laptop to search for things including bullying and to look up "Top 10 evil children" and "Super Columbine Massacre Role Playing Game."

Allen said images on Reyes' phone had photos of violent wars scenes and pictures of the Columbine High School shooters.

Police also said the parents, Jose and Liliana Reyes, would not be charged with a crime.

"They did not believe their son had any interest in firearms and he was not a child that acted in violent or aggressive behavior," Allen said.

The gun used, one of two from the Reyes' apartment in Sparks, were kept in a cabinet above the refrigerator behind cereal boxes.

Liliana Reyes told police that after hearing about the shooting at Sparks Middle School from a family member who called, she looked at the kitchen cupboard where the two guns were kept.

She realized the cereal boxes had been moved and she called her husband.

The 12-year-old Reyes also wrote two notes that police found in a spiral notebook inside the orange backpack he took to school that morning.

In the notebook with the Angry Birds video game characters on the cover, Reyes tells his parents he is sorry.

"Dear mom and dad I'm sorry about all this is because some of my family and friends hate me but I understand. What I did this shooting is not because of the shooting games, bullying or other stuff is because of the past causes there some bad things in the past cause of me. And now I'm just a monster..." the handwritten letter begins.

He ends the letter to his parents, "But I love you and I wish the past would be good and better someday."

Allen said the notes give conflicting motivation for the shooting but both suggest that his life would end in the process.

The report outlined cases of bullying.

Although police had multiple reports that Reyes had been teased and bullied, they had a difficult time pinning any students down on the details of those incidents, including the names of the offenders and the specific bullying actions.

Three students recounted an incident in the locker room where Reyes was drinking from a water bottle and a student knocked it out of his hands. The group then laughed and teased him for looking as if he had urinated in his pants.

"No evidence was identified that indicated Reyes was bullied by the definition of state law," the report said. "However, it is clear on numerous occasions he was treated poorly, teased, called names and mocked by other students."

In the letter to teachers and students, Reyes writes he would get revenge.

"Dear teachers and students today is the day when I kill you bastards for the embarressment that you did. You say mean things in school. That I'm gay. That I'm lazy. Stupid. Idiot and also say I pee my pants and also stealing my money. Well that all ends. Today I will get revenge on the students and teachers for ruinning my life... And right now this school will now come to an end your death will be rising when I shoot you. Have a great death at school."

Intercom didn't work

The report includes witness statements ranging from those at the school on Oct. 21 to teachers the student had in elementary school.

The day of the shooting, students and teachers describe running in fear, some hopping fences around the school or tripping as they tried to reach safety.

Then-Principal Stacy Cooper was inside the school when a crowd of students began running toward her, saying that someone was shooting.

She called Code Red on her radio and called 911, but the intercom wasn't working when she attempted to announce Code Red to the rest of the school. She told police it was common for the intercom system to not work.

Cooper said she was familiar with Reyes because he had a history of "angry outbursts" at Agnes Risley Elementary School. She told police she wasn't aware of any bullying reports.

"We were playing catch, and I heard a loud pop," one student witness wrote. The student in his own messy handwriting describes seeing Reyes aim the gun at Landsberry and shoot. "He fell to the ground, then I ran."

In an interview, Sparks Middle School Vice Principal Jerry Endres told police he went to Landsberry saw he was dead, turned when he heard a gunshot and saw Reyes pointing the gun at him.

He said he believed Reyes was chasing him and as he ran, he fell. He hid behind a planter until he was able to get into the school.

Endres also tried to call Code Red over the intercom, but it wasn't working. He then went into the cafeteria with a group of students and stacked garbage cans in front of the door.

What boy's parents said

The report also includes details from interviews with Liliana and Jose Reyes, who describe a son they loved but knew struggled.

They said he didn't start talking until he was 5.

In the report, the boy's mother first asked for help from school officials when Reyes was in fourth grade.

The parent involvement facilitator at the school said she helped with two parent-teacher meetings on the subject, which she said ended positively.

Teachers at Agnes Risley first noticed emotional problems with Reyes in second grade. They said he would often cry and they would take him for walks around the school to help him calm down.

Reyes' fourth-grade teacher, Kelly Lorenzetti, described him as "always smiling, always willing to help and very quiet." She also said he had few friends.

Lorenzetti told police Reyes had been diagnosed on the autism spectrum.

Christy Bartlett, a special education teacher who worked at Agnes Risley Elementary School, said Reyes would often believe he was being teased when children were reacting to something different.

She said the kids at the elementary school "cared for Jose and did not let people pick on him because of his speech or academics."

Bartlett told police that Reyes had a difficult time calming down once he became angry. He once threw a chair against a wall when he thought a student was teasing him, she said.

Bartlett said she recommended that Reyes be placed in a life skills class, but the recommendation was denied by the program manager.

The report provides some of the earliest clues to what police described as a suspect that struggled with verbal communication skills as early as kindergarten.

In one note from school counselors, it appears a Washoe County School District employee is worried about how Reyes will manage in middle school.

"He is very low academically and cognitively and also gets frustrated and upset when he is confused or does not understand something," she writes. "I am worried about his ability to handle middle school."

In the report are many details that combined point to a child who had difficulties.

Also, three days before the shooting, Reyes was prescribed a generic form of Prozac by local psychotherapist Garen Mirzaian.
